Drag & drop between two lists in different components

[f-jiang]

Is it possible for drag & drop to work when each list is contained within its own component?

I currently have code like the following. On a visual level, drag & drop works (except that items transferred between lists don't show up until a second item is transferred), but the items arrays' actual contents don't change.

Parent component:

import { Component, OnInit } from '@angular/core';
import { ItemsService } from '../items.service';

@Component({
  selector: 'app-multi-list',
  template: `
<h2>Drag / drop the item</h2>
<h3>list 1</h3>
<app-list [(items)]="itemsService.items1"></app-list>
<h3>list 2</h3>
<app-list [(items)]="itemsService.items2"></app-list>

<hr>

<h2>See the result</h2>
<div>
  <h3>list 1</h3>
  <div *ngFor="let item of itemsService.items1">{{ item }}</div>
  <h3>list 2</h3>
  <div *ngFor="let item of itemsService.items2">{{ item }}</div>
</div>
`,
  styleUrls: ['./multi-list.component.css']
})
export class MultiListComponent implements OnInit {

  constructor(public itemsService: ItemsService) { }

  ngOnInit() { }

}

Child component that contains a sortable list:

import { Component, Input, OnInit } from '@angular/core';
import { SortablejsOptions } from 'angular-sortablejs';

@Component({
  selector: 'app-list',
  template: `
<div [sortablejs]="items" [sortablejsOptions]="{ group: 'test' }">
  <div *ngFor="let item of items">{{ item }}</div>
</div>
`,
  styleUrls: ['./list.component.css']
})
export class ListComponent implements OnInit {

  @Input() items: any[];

  ngOnInit() { }

}

Hi @f-jiang

could you reproduce it, please, within a fork of a demo project?

Could you please let me know how can we drag and drop items from left component to right component.
